United States Patent 3,211,344 TIPPING COOKING VAT Lars Gustaf. Ekman, 17 Banergatan, Stockholm, Sweden, and Karl Erik Berg, 15 Fannydalsvagen, Nacka, Sweden Filed May 16, 1962, Ser. No. 195,264 Claims priority, application Sweden, May 18, 1961, 5,208/ 61 4 Claims. (Cl. 222-166) This invention relates to a tipping cooking vat adapted to be emptied over'its rim preferably provided with a pouring lip into, for example, smaller vessels by turning the vat about a fixed horizontal axle mounted in a fixed stand.

Vats of the aforesaid type are usually emptied of their contents, such as cleaning water or the like, into a sink well in the floor in front of the vat. It is the object of this invention to eliminate the need of such a sink well, because such a well is not only complicated and expensive to lay, but also causes considerable cleaning problems in view of its location below the floor and, moreover, gives rise to sanitary inconveniences when it is not cleaned frequently and carefully.

The invention eliminates the need of such a sink well in connection with a cooking vat of the aforesaid type in that the vat is arranged such, that it may also be emptied into a waste arrangement in the form of a funnel or the like mounted above the floor and connected to a waste vessel or Waste pipe, in such a manner, that the funnel may be moved into or is located in connection with the rim or the pouring lip of the vat, so that upon emptying the vat the water and the like flows down into the waste funnel from where it is discharged into the normal waste system.

The invention is described in the following, reference being had to the accompanying drawings showing by way of example several embodiments of the invention, whereon FIG. 1 shows a vat according to the invention seen from the front,

FIG. 2 shows the vat seen from above,

FIG. 3 shows the vat seen from the side, and

FIG. 4 is a side view of a somewhat modified embodiment of the vat according to the invention.

Referring to FIG. 13, the vat proper is designated by 1 and a steam casing or like heating arrangement by 1B. The vat 1 is emptied through a pouring lip 2 formed at the upper rim of the vat and has a flange 3 and a bearing 4 whereby it is mounted for tipping in a fixed stand 5. The tipping or emptying motion of the vat is effected by a hydraulic lifting cylinder 6 comprising a piston rod 7 connected to the piston of the said cylinder. The cylinder is preferably connected to the water main. A funnel 8 in front of the vat 1 is preferably in rotary and detachable attachment with a waste line 9-11 comprising a water seal 10, and may, if necessary, be provided with a filter 12, see drawing, which may possibly be connected with an extension piece 13 serving as a splash guard. The funnel 8 may be fixed in its position relative the pouring lip 2 by an arrangement 14, as shown schematically.

The funnel 8 may be arranged between two vats, in such a manner, that it can be swung into a position in front of either vat.

In the embodiment of the vat according to FIG. 4, the details which are identical with those of the embodiment according to FIGS. 1-3 are given the same reference numerals as in FIGS. 1-3. As appears from FIG. 4, this embodiment differs from that according to FIGS. l-3 only in the construction of the waste arrangement mounted above the floor. According to FIG. 4, the waste ice funnel is box-shaped and comprises a portion 15 which is firmly connected with the waste pipe 9-11 and preferably also with the stand 5, and a portion 17 mounted on a horizontal axle 16 and adapted to be swung outwards relative to the fixed portion 15. The said portion 17 may, as indicated by 17A and 17B, be moved into an outer position 17A for emptying the vat into the waste funnel, and into an inner position 17B in which position the portion 17 lies inside the front rim of the pouring lip 2 and will thus not be in the way when vat 1 is to be emptied into, for example, smaller vessels. Even in this embodiment, there is an extension piece 18 which in this case may be drawn out as much as desired.

The two aforesaid embodiments have in common that the tipping motion and direction of vat 1 are the same both for emptying the vat into vessels and into the funnel 8 and 15-17 respectively mounted above the floor.

The said funnel is in both embodiments mounted directly on the vat stand 5, close to and straight below the pouring lip 2. This arrangement is particularly expedient, as the invention in the examples shown is applied to a cooking vat mounted on a horizontal axle located close to the pouring lip 2, so that the lip during the tipping operation performs only a very limited movement.

Due to its detachability, the funned according to the examples shown is easy to clean. It may possibly be common to several vats.

The waste line may, when desired, be provided with a waste crusher or the like mounted before the water seal. Such crushing device is particularly advantageous for a waste line serving several vats, as it thus will crush the waste from a plurality of vats.

The aforedescribed embodiments of the cooking vat are to be considered as examples which with respect to their details may be modified within the scope of the invention as it is defined in the following claims. The invention is, for example, not limited for use in connection with front rim mounted vats, but may even be applied to laterally suspended vats of conventional type, which are mounted in connection to a line through the center of gravity. It is further possible to secure the vat stand in the wall behind the vat (console mounting) and to draw the waste line, like the other lines, to the rear.

It must, finally, be observed that the construction and location of the waste funnel within the scope of the inventive idea is to be varied in view of the shape, size, type of stand and mounting of the vat.

What we claim is:

1. A tipping cooking apparatus comprising a fixed supporting structure, a vat having a rim at its upper edge provided with a flange extending along one side of said rim, a pouring lip portion over which said vat is adapted' to be emptied by turning the vat about a fixed horizontal axis afforded by a stationary supporting structure, said vat being pivotally mounted in fixed bearings disposed at the same side of the center of gravity of the vat as said pouring portion of the rim thereby to cause small movements of the latter during tipping movements thereof to discharge its contents into a receiving vessel, a drain conduit, a drain funnel being mounted above the floor in fixed bearing means by which it is turnable away from position for receiving the contents of the vat into position near said pouring portion of the rim and connected to said drain conduit so that, upon emptying the vat into said funnel, the water and the like flows into said drain conduit, the tipping motion and the tipping direction of the vat being the same both for emptying the vat into said vessel and into said drain funnel.

2. A tipping cooking vat apparatus comprising a fixed supporting structure, a vat having a rim at its upper edge provided with a flange extending along one side of said rim, a pouring lip portion over which said vat is adapted to be emptied by turning the vat about a fixed horizontal axis afforded by said fixed supporting structure, said vat being pivotally mounted in fixed bearings disposed at the same side of the center of gravity of the vat as said pouring portion of the rim thereby to cause small movements of the latter during tipping movements, a drain conduit, a drain funnel being mounted above the floor near said pouring portion of the rim directly on said fixed supporting structure and connected to said drain conduit, said drain funnel comprising a first portion which is firmly connected to said drain conduit and to said fixed supporting structure, and a second portion which is pivotally mounted on a fixed horizontal axis and turnable inwardly toward said first portion away from position for receiving the contents of said vat, and outwards relative to said first portion, so that upon emptying the vat the water and the like flows away by way of said funnel and said drain conduit, the tipping motion and the tipping direction of the vat being the same both for emptying the vat into vessels and into said drain funnel.

3. A tipping cooking vat according to claim 2, and in which the said second portion is provided with a telescopic extension piece adapted to be drawn out.

4. A tipping cooking apparatus comprising a fixed supporting structure, a vat having a rim at its upper edge provided with a flange extending along one side of said rim, a pouring lip portion over which said vat is adapted to be emptied by turning the vat about a fixed horizontal axis afforded by said fixed supporting structure, said vat being pivotally mounted in bearings disposed at the same side of the center of gravity of the vat as said pouring 4 lip of the rim and close to said pouring lip thereby to cause small movements of the latter during tipping movements for emptying its contents in a vessel, a drain conduit, a drain funnel mounted above the floor close to and directly below said pouring lip portion of the rim directly on said fixed supporting structure and connected to a drain conduit, said drain funnel comprising a first portion which is firmly connected to said drain conduit and to said stationary supporting structure, and a second portion which is mounted on a fixed horizontal axis and turntable inwards toward said first portion away from position for receiving the contents of said vat, and outwards relative to said first portion, so that upon emptying the vat the Water and the like flows away by way of said funnel and said drain conduit, the tipping motion and the tipping direction of the vat being the same both for emp tying the vat into said vessel and into said drain funnel.
